SHUTTER-BOLT.

SPECIFICATION forming part of Letters Patent No. 618,958, dated February'7, 1899.

Application filed November 25, 1898. Serial No. 697,361. (No model.)

To a'ZZ whom it may concern:

Be it known that I, HENRY L. LAPP, a citizen of the United States,residing at Bird in Hand, county of Lancaster, State of Pennsylvania,have invented certain Improvements in Shutter-Bolts, of which thefollowing is a specification.

This invention relates to improvements in that class of bolts designedfor securing window-shutters; and the objects of the invention are,first, with the same bolt to lock the shutters in a closed position orto secure them in any bowed position desired, and, second, to secure theshutters firmly in a fully-open position. 1

There are bolts in use divided into sections one of which is attachedtoeach of the shutters and with which the shutters are held in a bowedposition by engaging a hook on the outer end of one bolt-section with aneye on the outer end of the other bolt-section; but there is more orless difficulty always experienced in disconnecting the hook from theeye, and in so doing the hook is very liable to be broken off. My boltovercomes these difiiculties.

My invention consists in the construction and combination of the variousparts, as hereinafter fully described and then pointed out in theclaims.

In the accompanying drawings,which form a part of this specification,Figure 1 is a horizontal sectional view of the shutters and a top viewof a bolt embodying my invention, the parts being shown in the positionoccupied thereby when the shutters are bowed.

V Fig. 2 is a similar section of the shutters closed, but showing thebolt in the position occupied thereby when the ends of the boltsectionsare to be disconnected, as seen in the parts shown by broken lines a: m.Fig. 3 is an inner face view of the'closed shutters, the bolt lockingthem in that position. Fig. 4 is a top sectional View of one of theshutters, showing the same locked in an open position against the wallof the house; and Fig. 5 is a side view of the wall=keeper on brokenline 5 5, Fig. 4, showing aside view of one of the wall-keepers. Fig. 6is a transverse section of the case of one of the bolt-sections.

Referring to the details of the drawings, A indicates the shutters, andA the wall of ahouse. There is a bolt-case B and B, respectively, oneach shutter, each of which boltcases is formed of a plate of flexiblemetal struck up lengthwise of the center to form a channel D and lips orflanges Don the sides of said channel, through holes in which thebolt-case is secured to the shutter by screws 12, as seen in Fig. 3. Itis not necessary that the bolt-cases be constructed as described, asthey may be formed of cast metal consisting of a flat plate extendingcontinuously from side to side and having channels cast integraltherewith.

E E indicate bolt-sections secured, respectively, in bolt-cases B and B,in which they have both a longitudinal and an oscillating movement. IThe extremities of the outer ends of these bolt-sections are halved intheir contiguous faces, and on the lip thus formed on bolt-section E isa stud 6, adapted to be en gaged in an opening through lip e ofboltsection E when said bolt-sections are turned with their lips in avertical position, as shown in full lines in Fig. 2.

Through the outer walls of channels D are longitudinal slots (1, throughwhich pass clamp-screws F, which engage threaded holes in thebolt-sections. The clamp-screws have annular flanges f, which areadapted to engage the edges of slots 01 to secure the boltsections in anadjusted position, and on said screws, outside of flanges f, arehandholds f. In the lower edge of each slot 61 is a notch 01',constructed to receive the projecting portions of clamp screws F whenthe bolt-sections are turned in their channels to throw the lips thereofinto a vertical position.

In operating when it is desired to how the shutters the bolt=sectionsare turned,with the 'clampscrews engaging the notches in the lower edgesof the slots in the bolt-cases, so as to place the lips on saidbolt-sections in a vertical position, as shown by broken lines Z, Fig.3, and stud e is engaged in the opening in lip e, as shown in full linesin Fig. 2. The bolt-sections are then turned to throw the lips into ahorizontal position, the shutters are opened to the desired width, andthen the clamp-screws are tightened up, as shown on the left of Fig. 1.To disconnect the boltsections, the clamp-screws are loosened, as

seen on the right of Fig. 1. Said bolt-sections are turned to throw theclamp-screws into said notches and the lips on said bolt-sections into avertical position, and the shutters are then moved to disconnect stud efrom the opening in lip e. To look the shutters in a closed position,both bolt-sections are moved in their channels until their united endsengage one of said channels, and there they are clamped fast, as seen infull lines in Fig. 3.

0n the outer face of wall A, somewhat outside of the line occupied bythe swinging edge of the shutter when fully open, is a keeper G inposition to be engaged by the bolt-section on the shutter. The innerbearing-surface of the keeper is tapered, so that the shutter is forcedfirmly against the wall when the bolt-section is engaged with saidkeeper, as shown in Figs. 4 and 5.

I do not restrict myself to the details of construction herein shown anddescribed, as it is obvious that many alterations may be made thereinWithout departing from the principle and scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combinatiomwith a pair of shutters, of a bolt-section connectedwith each shutter and having a longitudinal and an oscillating movementin its case, and a stud on the outer end of one bolt-section and adaptedto engage an opening in the outer end of the other bolt-section, for thepurpose specified.

2. The combination, With a pair of shutters, of a bolt-section connectedwith each shutter and having a longitudinal and an oscillating movementin its case, the outer ends of the bolt-sections having lips formedthereon and constructed to lap one over the other, and a stud on one ofsaid lips and adapted to engage an opening in the other lip, for thepurpose specified.

3. The combination, with a pair of shutters, of a bolt-case on eachshutterand having a longitudinal slot therein, notches being formed incorresponding edges of the slots, a bolt-section in each bolt-case,clamp-screws passing through the slots in the bolt-cases and engaging inthe bolt-sections, lips on the outer ends of the bolt-sections andconstructed to lap one over the other, and a stud on one of said lipsand adapted to engage an opening in the other lip, substantially as andfor the purpose specified.
